Hi guys,
I ve had my Revo map on my car for the last 2 years, but when i first had it i disconected the battery when fitting a sub. didnt realise it wud knock the map off. the guy who mapped it said he will put it back on but only that once and he would charge the next time it happend.
Anyway.
my Battery had now had it and need a new one, how can i get around not loosing the map again??
The guy in Halfords said they have a thing that they plug into the cigarette lighter that still puts charge around the car to stop loosing all the info from the radios and stuff but will that work for the map??
Thanks
Jon
